Safer sites. Clearer site access.

Andatech helps construction companies manage alcohol and drug risk through on-site testing, workplace equipment, policy support, collector training, cloud reporting and calibration programs.

Construction sites carry risk before work starts. Crews move between plant, vehicles, scaffolding, tools, traffic zones and public interfaces. Alcohol or drug impairment can affect coordination, judgement and reaction time in areas where one error can harm several people.

A strong program does more than screen workers. It gives site leaders a clear policy, trained people, reliable equipment, consistent records and a fair response process. Andatech helps construction companies connect those parts so testing supports daily site safety.

Construction site risks that need a clear testing program

  • High-risk work

    Construction teams work around plant, vehicles, power tools, heights and changing site conditions. Impairment can increase the chance of injury, equipment damage and work stoppages.

  • Mixed site workforces

    Principal contractors often manage employees, subcontractors, labour hire teams and specialist trades on the same project. A narrow policy can leave gaps in site access and incident response.

  • Legal and financial exposure

    A serious incident can trigger WHS investigations, project delays, insurance pressure and client concern. Clear records help leaders show how they managed known risk.

  • Site entry pressure

    Testing needs to work during pre-start and shift changes. Slow manual checks can create queues and delay work crews.

Maintain an alcohol and drug-free work environment for your workers

A construction testing program should explain who the policy covers, when testing occurs, which method applies and how the business handles non-negative results. Pre-access testing can support site entry rules. Random testing can help reinforce ongoing expectations. Post-incident and reasonable suspicion testing can help supervisors respond to risk signs. Pre-employment and return-to-work testing can support recruitment, reinstatement and support pathways.
